Pretty much what I get from reading all this is:
1. Gaia is hopefully going to be giving us oodles of cool information about space and the stuff that’s out there in it.
2. Brown Dwarves are a real thing, and also, despite their name, are entirely unrelated to Tolkien or D&D.
3. Einstein’s General Theory of Relativity continues to be poked and prodded by science. Meanwhile, Hofstadter’s law continues to appear unavoidable.
